Test fabric porosity

Measurement of the air permeability of the fabric

15 Euro Porosity test

Good fabric porosity levels are required for your wing to keep the internal pressure high enough to maintain average resistance to collapse and parochial tendencies.

We use POROZIT N from Hello Ltd and take measurements in 3 places on the top surface, 10 – 20cm from the leading edge. If readings are low or inconsistent, further readings are taken.
